' Filed March 21, 1928 Patented F eb. 24, 1931 FRANK L. MICHAELS, OECOVINGTON, KENTUCKY METAL WINDOW AND WEATHER STRIP Application filedMarch 21, 1928. Serial No. 263,248.

My invention relates to improvements in met-a1 window frame sash andWeatherstrip. One of its objects is to provide an improved combinationof metal window frame sash and 5 Weatherstrip. Another object is toprovide an improved arrangement of frame sash and. Weatherstrip in whichthe wind pressure from without tends to more tightly close theWeatherstrip joints to eifectively exclude wind and water. Anotherobject is to provide and adapt improved weatherstrips to metal windowframes and sashes produced from mitered sections of stock bars ofextruded metal of specially provided cross-sectional design. Myinvention also comprises certain details of form and arrangement andcombination of components, all of which will be fully set forth in thedescription of th accompanying drawings, in which:

Fig. 1 is an inside elevation of a wlndow frame and sash embodying myimprovements.

Fig. 2 is an enlarged vertical section taken on line 22 of Fig. 1.

Fig. 3 is an enlarged sectional vlew'taken on the line 3-3 of Fig. 2.

The accompanying drawings illustrate one embodiment of my invention inwhich 15 represents the cap, 16- and 17 the side rails, and 18 the sillor ledge of a window frame, said frame being constructed from extrudedmetal, by cutting long bars thereof of especially designed cross-sectioninto sections of the desired length and uniting said bar sections bybrazing or similar means into a window frame. Guideways or channels 19and 20 are provided along theinside of the side rails 16 and 17 to guidethe vertical movements of the respective sash members 22 and 23. Avertical channel 24 in each of the side rails 16 and 17 provides a seatinto rwhich the base of a detachable vertical parting strip or guidestrip 25 together with a thin flexible strip of sheet metal Weatherstrip26 enter and are held in place by means of a series of screws 27, whichare threaded into perforations in the side rails 16 and 17. The uppersash is guided in its vertical movements between the ledges 28 of thesiderails 16 and 17 and the guide strips 25 attached to said side rails16 and 17.

The vertical window bead or guide strips 30 and flexible sheet metalweatherstrips 31 are held detachably in place relative to the side rails16 and 17 to form channels 20 between the guide strips 25 and 30 bymeans of a series of screws 32 threaded into perforations in the siderails 16 and 17 The sash 23 moves vertically in the guideways 20 relacotive to the window frame. The window frame is adapted to he set in brickor stone masonry or tobe set in a wooden framework as may be desired.Across the inside of the cap section 15 of the window frame is a chano5nel 33 in which is detachably seated a cross bar 34, of cross sectionsimilar to that of the guide strips 25, and a flexible sheet metalWeatherstrip 35. The top edge of the upper sash when in closed positionenters between a ledge 36 on the cap section 15 of the win-' dow frame,and the cross bar 34 and weatherstrip 35, as shown in Fig. 2. The crossbar 34 is detachably held in place by means of a series of screws 36.The upper sash 22 is built up from short mitered sections of extrudedmetal cut from stock bars of metal of especially designed crosssectional pattern substantially as shown. A glass panel 37 is mounted inthe upper sash 22, and held in place therein by means of strips 38,detachably held in place by screws 39 or similar means. The crosssectional pattern of the lower cross bar of the upper sash at 40 issomewhat different from the cross sectional pattern of the top and sidesections of the sash 22, in order to provide for making a weather proofjoint between the lower edge of the upper sash and the upper edge of thelower sash. The 0 ening across the bottom of the lower cross ar of theupper sash is closed by means of an extruded metal strip 41, which isadapted to be inserted endwise or telescopically into place and tointerlock with the edges of said lower cross bar substantially as shownin Fig. 2.

The lower sash is constructed from short mitered sections of an extrudedmetal bar of substantially the same cross sectional pattern, andsubstantially as described for the to make a wind and water proof jointbe-' tween the two sashes where they meet. Any wind pressure upon thisWeatherstrip 43 from outside of the sashes tends to hold theweatherstrip 43 more firmly in engagement with the lower portion of theupper sash. The

' strip 42 may be detachably locked to the ledge 44 by means of screws45.

lVhere the lower cross bar of the lower sash comes in contact with thesill 18 of the window frame 18, a flexible sheet metal Weatherstrip 47is detachably held in place between the sill 18 and the strip 48, andmay be. detachably held in place by means of screws 49. The free edge ofthe strip 47 bears resiliently against the face of the lower cross barof sash 23 substantially as shown in Fig. 2. Any wind pressure fromwithout is adapted to act upon the strip 47 to press it more firmlyagainst the lower cross rail of sash 23. The weatherstrips 26, 31 and 35are also so arranged that any wind pressure from the exterior exerts apressure upon the rear face of said strips so as to tend to close theWeatherstrip joint more eflectively. A glass panel 50 is held in placerelative to the lower sash by means of detachable metal strips 51secured in place by means of screws 52.

The apparatus herein shown and described is capable of considerablemodification within the scope of the claims without departing from thespirit of my invention.

What I claim is:

1. A metal window structure comprising a metal window frame, metal sashmembers,

metal guide strips detachably attached to said window frame and formingvertical guide channels to guide the movements of said sash membersrelative to said window frame,afiexible metal Weatherstrip at themeeting edges of said sash members, detachably attached at one edge tothe cross rail of one of said sash members and with its free ed ebearing resiliently upon the cross rail 0 the opposite sash member, therelation of said sash members and Weatherstrip being such that windpressure from the exterior of said window tends to hold the free edge ofsaid weatherstrip more firmly in engagement with the opposite sashmember.

2. A metal window structure comprising a metal window frame, metal sashmembers, metal guide strips detachably attached to said window frame andforming vertical guide channels to guide the movements of said sashmembers relative to said window frame, a

flexible metal Weatherstrip at the meeting edges of said sash membersdetachably attached at one edge to the top cross rail of the gaging thelower cross rail of the upper sash member, the relation of said sashmembers and Weatherstrip being such that wind pressure from the exteriorof said window tends to hold the free edge of said Weatherstrip morefirmly in engagement with the opposite sash member.

3. A metal window structure comprising a metal window frame, metal sashmembers, metal guide strips detachably attached to said window frame andforming vertical guide channels to guide the movements of said sashmembers relative to said window frame, a flexible metal Weatherstrip atthe meeting edges of the lower sash with the sill of said window framedetachably attached to said sill member by means of a metal bindingstrip secured across the top of said sill, and with the free edge ofsaid Weatherstrip extending, downwardly between the sash member and silland resiliently engaging the lower cross rail of said sash member, therelation of said sash member, sill and weatherstrip being such that windpressure from the exterior of said window tends to hold the free edge ofsaid Weatherstrip more firmly in engagement with said sash member.

4. A window structure comprising a window frame, window sashes, verticalguide strips detachably attached to the side rails of said window frameto form vertical guide channels to guide the movements of said sashmembers relative to said window frame, vertical recesses between saidsash members and said guide strips, and flexible metal weatherstripsattached at one edge to said window frame by said guide strips andhaving their free edges looped upon themselves within said verticalrecesses with one side of said loops bearing resiliently against theside rails of said sash members and the other side of said loops bearingresiliently against said guide strips.

5.
